Eindhoven University of Technology (TU/e) is a young university, founded in 1956 by industry, local government and academia. Today, their spirit of collaboration is still at the heart of the university community. We foster an open culture where everyone feels free to exchange ideas and take initiatives.
Eindhoven University of Technology offers academic education that is driven by fundamental and applied research. Our educational philosophy is based on personal attention and room for individual ambitions and talents. Our research meets the highest international standards of quality. We push the limits of science, which puts us at the forefront of rapidly emerging areas
Eindhoven University of Technology combines scientific curiosity with a hands-on mentality. Fundamental knowledge enables us to design solutions for the highly complex problems of today and tomorrow. We understand things by making them and we make things by understanding them.
Our campus is in the centre of one of the most powerful technology hubs in the world: Brainport Eindhoven. Globally, we stand out when it comes to collaborating with advanced industries. Together with other institutions, we form a thriving ecosystem with one common aim - to improve quality of life through sustainable innovations.
The Electromechanics and Power Electronics group is one of the nine research groups of the Department of Electrical Engineering at TU/e. The group is the main centre for research in electromechanical power conversion and power electronics in the Netherlands. The research is aligned with the three main strategic research themes of Eindhoven University of Technology,
i.e. Energy, Health and Smart Mobility.
This PhD position is part of the HiEFFICIENT Research and Innovation Action, an interdisciplinary European Joint Undertaking project with 21 involved companies, 3 research institutes and 9 academic institutions. Within HiEFFICIENT the project partners will work towards the goals of the European 'Green Deal' initiative that strives for sustainable mobility and efficient use of resources. The goal is to develop the next generation of wide bandgap semiconductors (WBG) in the area of smart mobility. The partners will work in industrial use cases to demonstrate key achievements of using WBG semiconductors and the progress that goes beyond state of the art. This includes, amongst others, modular inverters with different voltage levels, multi-purpose DC/DC converters and test systems for power electronics'
TU/e will be involved in Use Case 4 (Multi-use DC Chargers) and Use Case 6a (Modular low-power DC/DC converter for vehicle solar panels). The use of WBG materials such as SiC and GaN enables high switching frequencies and steep rising edges (dv/dt), as well as high voltages. These characteristics enhance the efficiency of switching power supplies. However, a steep dv/dt increases the challenge to meet electromagnetic interference (EMI) compliance, and potentially causes over-voltages and insulation problems in drivetrains.
Based on the overall objectives of HiEFFICIENT -- higher integration, efficiency, and reliability --, the PhD candidate will investigate possible solutions to accurately control the dv/dt of the switching nodes in the power processing converters by applying soft-switching based auxiliary circuits, instead of using conventional voluminous and lossy dv/dt filters. Compared to a conventional hard-switched converter with dv/dt limiting ﬁlters, it is expected that the fast charging system with controlled voltage edges will achieve a quite large reduction in inductor volume, filter weight and in overall power loss.
Your main research directions will be:
- Modelling and design of alternative WBG-based stacks by adding soft-switching circuits in order to verify the benefits of accurate control of fast dv/dt flanks, with respect to efficiency, volume reduction and EMI compliance.
- Build and test the designed solutions to compare with the benchmark hard-switching converter prototypes as realized by the other project partners.
As a PhD student, you will be working in the Electromechanics and Power Electronics (EPE) group in the Electrical Engineering department. Weekly meetings will be held with the direct supervisors, and regular meetings will occur with the academic and industrial project partners.
The PhD candidate for the HiEFFICIENT project should fulfil the following requirements:
- MSc degree in Electrical Engineering
- Strong affinity and experience with power electronics
- Affinity with the following topics: circuit layout technology, magnetic design,
state-of-the-art digital control, electromagnetic compatibility and thermal performance for power electronics
- Strong analytical and research skills, both regarding theoretical work and experimental validation
- Excellent communication skills
- Ability to independently organise his/her own work, to solve problems, to set and achieve goals and to cooperate with others
- Willingness and ability to participate in the education in BSc and MSc programs
(both taught in English)
- Good scientific writing and documentation skills
- Strong command of the English language, both spoken and written.
- A meaningful job in a dynamic and ambitious university with the possibility to present your work at international conferences.
- A full-time employment for four years, with an intermediate evaluation after one year.
- To support you during your PhD and to prepare you for the rest of your career, you will have free access to a personal development program for PhD students (PROOF program).
- A gross monthly salary and benefits in accordance with the Collective Labor Agreement for Dutch Universities.
- Additionally, an annual holiday allowance of 8% of the yearly salary, plus a year-end allowance of 8.3% of the annual salary.
- A broad package of fringe benefits, including an excellent technical infrastructure, moving expenses, and savings schemes.
- Family-friendly initiatives are in place, such as an international spouse program, and excellent on-campus children day care and sports facilities.
